Listingbook allows agents to register their buyers and sellers to give them access to a web-based application with client-based functions such as listing searches and CMA reports. Agents who select upgraded versions of Listingbook can take advantage of behind-the-scenes functions such as marketing tools and client-activity tracking.

The application is owned — and supported — by Listingbook™ LLC. ORRA's agreement with Listingbook™ LLC specifies that Listingbook™ LLC will provide ORRA members with free access to the basic level of Listingbook and with unlimited free technical support.
